Infrared Methodology for Bringing CPE Baseband Signal Into

Buildings Without Drilling Holes

By William Meitzler


A new customer that wants Satellite TV or Broadband Internet Service installed will hire an installer come to his house. The installer will mount a box on the side or roof of the house and drill a hole through the siding or roof to fix one physical point of data entry into the home through a coaxial cable. The "box" could be a millimeter wave fixed terrestrial consumer premesis equipment (CPE), a satellite dish, or a distribution box for underground coax or fiber. Two disadvantages are found in this process.

1.) The installer is expensive and most customers do not like to schedule special visits.

2.) The installation point is physically fixed. The customer must install an in-house LAN or run coax cable inside the house to move the broadband signal from room to room.

This document describes a method that provides the customer the following advantages.

1. The installer only needs to come once in order to mount the "box" and supply DC power to the box in compliance with local building codes.

2. Once the installer leaves, the customer can reconfigure his at-home communication system by himself.

3. There is no need to run cables across walls or under carpets as long as an outside window exists in the room where communication service is desired.

4. The invention uses infrared parts developed for the Personal Digital Assistant industry. The large volume of parts manufactured for the PDA industry will drive down part costs.

5. Landlords can tailor communication service to tenants as needed. The CPE remains fixed and is capable of servicing the entire building.


The outside radio equipment and antenna are mounted on the house once. The radio equipment has several baseband transceivers to provide service to different rooms. The residential premises software is configured to have each transceiver channel billed to an individually selected billable account. This will allow the same hardware to service single and multiple occupant dwellings. The purchaser of this equipment is given access to this software. Each transceiver is capable of delivering several channels of service through either frequency division or time division multiplexing schemes. The advantage of providing the multi-channel complexity is to allow the user to daisy chain several users onto one cable run. The radio equipment supplier may decide to provide separate optional transceivers for additional cable runs and not develop multiplexing methodologies.

The customer will need access to several coaxial cables of varying lengths. Standard 50 ohm cable such as presently used to television sets is used. The base station equipment provider may sell cable in a spool and cables, and rent the connector installation ki...
